Hi everyone, I've read some things about all of the PCIe slots not being usable and would like to ask the macphiles here before heading out to an Apple store to speak with a 'genius'... I'll soon be ordering a new MP and have six displays that I would like to run from it. Only one of them requires a dual link DVI (2560 x 1600), the rest are 1900x1200. Most of the work I do is web development with the most graphically intense program being photoshop - and only on the primary display. No video editing or hardcore CAD/graphics work. Any guidance on video card combos would be appreciated.
